DISK-OILER ATTACHMENT FOR CAR-AXLES.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed January 13, 1905. Serial No. 240,924.

To (all whom it may concern:

Be it known that I, LAVALETTE L. LOGAN, a citizen of the United States,residing at Bobertsdale, in the county of Huntingdon and State ofPennsylvania, have invented new and useful Improvements in Disk-OilerAttachments for Oar-Axles, of which the following is a specification.

This invention relates to a disk-oiler attachment for car-axles andjournals, and is particularly adapted for use in connection withmine-cars. The oiler embodying the features of the invention has beenspecially devised to meet contingencies affecting such devices, bothfrom a standpoint of structure as well as efliciency in operation.

The improved oiler is preferably cast or otherwise produced in one pieceand has an open top with an extension to receive the disk which isattached to the car-axle and to provide for a snugly-closing main bodyor receptacle by inserting the extension around the open top and whichis in the form of aflange in the under side of the bolster or otheradjacent truck structure of the car. The advantage in forming the mainbody or receptacle of the oiler inone piece is that it can be moreexpeditiously applied after disposition on the axle to the truck-frameor bolster or removed from the latter when repair of the truck, axle, orreplacement of a worn axle is found necessary. By having the open topformed with a surrounding extension or flange all dirt, grit, or othersubstance is prevented from entering the main body or receptacle whensuch extension is embedded in the bolster or truck-frame. Anotheradvantage of the open-top single-piece main body or receptacle is thatthe disk can be more easily inserted in position within such body forapplication to the axle, and, conversely, said disk may be by thesemeans more readilydetached.

Other objects and advantages will appear hereinafter, and it ispreferred also that the improved disk-oiler be used on a mine-carwherein each axle is rotatable, and has a wheel fixed to one extremityand a loose wheel on the opposite extremity. It will be understood,however, that the disk-oiler may be used in connection with other axleand wheel arrangements.

In the drawings, Figure 1 illustrates a transverse vertical sectionthrough a portion of a mine-car, taken in the plane of one axle andshowing the improved disk-oiler applied thereto and one wheel loose andthe other fixed with respect to opposite extremities of the axle. Fig. 2is an enlarged transverse vertical section of the disk-oiler shownapplied to a portion of an axle. Fig. 3 is an outer side elevation ofthe disk-oiler. Fig. 4: is a top plan View of the same. Fig. 5 is asection on the line 5 5, Fig. 4:. Fig. 6 is a detail view of anexpanding-key forming part of the means for securing the disk to thecaraxle.

Similar numerals indicate corresponding parts in the different views.

The numeral 1 designates a mine-car body having a bottom frame 2, whichmay be of any suitable form for supporting a rotatable axle 3. One wheelL is rigidly secured to the axle by a pin or bolt 5, and the other wheel6 runs loose on the axle. The object of this arrangement is to have thewheels run independently of each other, so that cars, particularl ymine-cars, can round short curves more readily, and in the event thatboxes are set on the bed or truck frame of the car slightly irregularlyor askew they will be forced to wear and fit neatly, and at all timesthe axle must turn and insure lubrication and very little turning of theloose wheel thereon, whereby wear of the wheel-hubs is reduced to aminimum and wabbling of the wheels prevented. The essential feature ofthe invention, however, consists, as before indicated, of a disk-oiler,including a main body or receptacle '7 of suitable proportions andcontour and having upper horizontall y-disposed securing-fianges 8,which are adapted to be bolted or otherwise secured to a truck-frame orthe end or bottom frame of the car. The fastening means employed forattaching the main body or receptacle 7 will be of such nature that theycan be readily removed. The chamber 9 of the body or receptacle hasbearings 10 projecting centrally thereinto from opposite sides, andleading to the said chamber is a filling channel or opening 11,accessible through one of the flanges and normally covered by a hingedclosure 12. The flange at the point where the filling channel or openingis located is enlarged or thickened to accommodate the formation of suchchannel, as clearly shown by Fig. 3. The top of the body or receptacleis open, and the opening is surrounded by an extension or verticalflange 13, which is adapted to be projected into a recess or seat 14,formed in the under side of the truck-frame or bottom framework of thecar, and when the body or receptacle has thus been applied and securedin place the chamber 9 will be fully closed and dust, dirt, or gritexcluded therefrom, and, furthermore, by the use of this extension orvertical flange any movement of the body or receptacle on the truckframeor body framework or bed of the car is prevented.

A disk 15 is included in the organization of the oiler and insertedthrough the open top of the chamber 9 in line with the bearings 10, saiddisk having a central opening 16, corresponding to the diameter of theaxle with which it is adapted to engage. After the disk 15 has beeninserted in the chamber 9 the oiler as an entirety is slipped over theend of the axle, the latter passing through the bearings 10 and theopening 16 in the disk. The disk 15 also has a pin-opening 17diametrically formed therein and communicating at one extremity with akey-seat 18, having an inner enlargement extending equally in oppositedirections beyond the end walls of the pin-opening to provide means forretaining an extensible key 19 therein. The outer portion of thekey-seat 18 is considerably less in length than the inner extension, andhence when the extensible key 19 is inserted in the seat and set it willbe prevented from becoming accidentally disengaged. At its oppositeterminal the pin-opening 17 communicates with a hole or opening 20 ofconsiderable less diameter than the width of the pin-opening for thereception and operation of a drift to remove'the pin. A pin 21 isinserted in the opening 17, and both the latter and the pin have arectangular contour, the axle being formed with a corresponding openingto receive the pin. The pin 21 is of such length that when it isinserted in the opening 17 the one end thereof will abut snugly againstthe inner terminal of the hole or opening 20 and the other end will beflush with the opposite terminal of the said opening 17. The key 19 inits normal condition is bent practically in V shape, so that the endswill pass into the outer portion of the seat 18, and after the said keyis thus disposed a sharp blow is given thereto and it is flattened, theterminals thereof projecting into the inner extensions of the seat 18,and thereby securing the pin 21 against accidental displacement. When,however, it is desired to detach the disk from the axle and remove thebody or receptacle, the disk is turned 'in such position that the holeor opening 20 will be readily accessible, and by means of small driftinserted in the said hole or opening against the adjacent end of the pin21 the auxiliary key 19 will be forced out of the seatlS and permit thesaid pin 21 to be withdrawn. The body or receptacle of the disk is thenremoved longitudinally off the adjacent end of the axle. The disk 15rotates in the longitudinal direction of the chamber 9 and is alwaysheld below the upper edge of the extension or flange 13 and at suchdistances from the opposite ends of the body or receptacle as to causethe surplus oil to fall back therefrom into the chamber 9.

From the foregoing description the operation of the device will beapparent. When the axle revolves, the disk picks up and continuouslydelivers the oil to the axle and is fed by the latter to the bearings10. The surplus oil between the opposite faces of the disk and the innerterminals of the bearings 10 on the axle will also fall back into thechamber 9, the parts being'so proportioned that there will be amplespace for this operation between the opposite faces of the disk and theinner ends of the bearings.

The improved oiler will be found exceptionally convenient in itsapplication and operation, as well as economical in the use of oil orother lubricant.

It will be understood that changes in the proportions, dimensions, andminor details may be resorted to without departing from the spirit ofthe invention.

Having thus described the invention, what is claimed is- 1.
